Abstract
The utility model discloses a landslide fissure measuring device which comprises a landslide fissure measuring scale and a landslide fissure measuring identifying nail. A semi-circle ring is arranged at the tail end of a flexible rule of the landslide fissure measuring scale. Cross-shaped wire is arranged on the top surface of a steel nail of the landslide fissure measuring identifying nail. An annular groove is arranged on the lower portion of the top surface of a steel nail. The landslide fissure measuring device is low in cost, convenient to operate and high in measuring precision.
Description
Technical field
The utility model relates to a kind of landslide fissure measurement mechanism, specifically, relates to a kind of landslide fissure dip stick and landslide fissure and measures the sign nail.
Background technology
Although landslide, avalanche, mud-stone flow disaster are sudden strong, harmfulness is large, and these disasters are gone to the past obvious omen that has.Carrying out the geologic hazard mass presdiction and disaster prevention, ordinary surveying is carried out in the crack of landslide, avalanche body and building etc., grasp the steady state (SS) of landslide, avalanche, is the effective ways that current China avoids casualties.
The simple and easy monitoring method of geologic hazard requires low, the easy installation of cost, easy to operate, easy care, mainly contains the pile anchoring method, buries the nail method, method of scoring, paster method, landslide fissure alarm method and landslide early warning pantograph method etc.When coming down, when avalanche trailing edge crack is obvious, can adopting the pile anchoring method, namely respectively bury a pile in the both sides, crack, with the distance between the steel tape measurement stake, understand landslide, avalanche deformation process at set intervals.
The monitoring of traditional pile anchoring method exists operating difficulties, problem that measuring accuracy is low:
(1) generally need 2 people to cooperate to draw steel tape in the process of implementing, operation easier is large;
(2) inconvenience accurately arranges and measures sign on the timber, and the duplicate measurements error is large.
The utility model content
In order to overcome the defective that exists in the prior art, the utility model provides a kind of easy and simple to handle, landslide fissure measurement mechanism that measuring accuracy is high, this device is transformed the ordinary steel tape measure, and the special landslide fissure measurement sign nail of design processing, improve and improve traditional pile anchoring method monitoring technology level.
Its technical scheme is as follows:
A kind of landslide fissure measurement mechanism, comprise landslide fissure dip stick and landslide fissure measurement sign nail, described landslide fissure dip stick is provided with a semicircular ring at the end of tape measure, and the steel nail end face that described landslide fissure is measured the sign nail is provided with crosshair, is provided with annular groove in steel nail end face bottom.
Further preferred, the diameter of described semicircular ring is 1.5cm.
Further, described landslide fissure measurement sign nail diameter is 1cm.
Annular groove described in the utility model is positioned at 0.5cm place, steel nail end face bottom.
The beneficial effects of the utility model:
When utilizing device of the present utility model to carry out the landslide fissure measurement, on the one hand, can hang by tape measure, easy and simple to handle by 1 personal work personnel complete independently, saved manpower; On the other hand, by groove suspension, crosshair reading sign, can greatly improve the precision of duplicate measurements.
Description of drawings
Fig. 1 is the structural representation of the utility model landslide fissure dip stick;
Fig. 2 is the structural representation that the utility model band landslide fissure is measured the sign nail.
Embodiment
Below in conjunction with the drawings and specific embodiments the technical solution of the utility model is described in more detail.
With reference to Fig. 1, Fig. 2, a kind of landslide fissure measurement mechanism, comprise landslide fissure dip stick and landslide fissure measurement sign nail, described landslide fissure dip stick is provided with a semicircle bad 2 at the end of tape measure 1, the steel nail end face that described landslide fissure is measured the sign nail is provided with crosshair 3, is provided with annular groove 4 in steel nail end face bottom.The diameter of described semicircular ring 2 is 1.5cm.It is 1cm that described landslide fissure is measured sign nail diameter.Annular groove 4 described in the utility model is positioned at 0.5cm place, steel nail end face bottom.
The utility model landslide fissure measurement mechanism is when concrete the use, stride the both sides, crack and bury two measurement stakes underground, measure the method for stake employing pvc pipe cement injection mortar, landslide fissure is measured sign nail nail be embedded in the measurement stake, expose top crosshair 3 and annular groove 4; After sand-cement slurry is solidified, can utilize the landslide fissure dip stick to measure.During measurement, the terminal semicircular ring of landslide fissure dip stick is suspended in the annular groove 4, stretching tape measure 1 is measured crosshair 3 places of sign nail to other end landslide fissure, and the dip stick reading is read in corresponding crosshair 3 centers, and record.During duplicate measurements, method is the same.
The above; it only is the better embodiment of the utility model; protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses, the simple change of the technical scheme that can obtain apparently or equivalence are replaced and are all fallen in the protection domain of the present utility model.
Claims (4)
1. landslide fissure measurement mechanism, it is characterized in that, comprise landslide fissure dip stick and landslide fissure measurement sign nail, described landslide fissure dip stick is provided with a semicircular ring at the end of tape measure, the steel nail end face that described landslide fissure is measured the sign nail is provided with crosshair, is provided with annular groove in steel nail end face bottom.
2. landslide fissure measurement mechanism according to claim 1 is characterized in that, the diameter of described semicircular ring is 1.5cm.
